Castroville is a Medina County town on US-90 west of San Antonio, founded by Alsatian settlers and known for its old stone houses. New subdivisions along the highway toward San Antonio, house pads on acreage and commercial lots at the town limits bring most of the earthwork, with La Coste to the east and Hondo to the west.
The Medina River loops around the old town, and its terraces carry sand, gravel and rounded river rock that make good fill and base. Higher up, off the terraces, the soil changes to clay loam over caliche. Rock-free sandy loam is the prize here for gardens, while river gravel goes into driveways and pads.
October rains return, and a single storm can shut down grading on the east side clay for most of a week. With the heat easing, hillside and pool jobs in the northern suburbs pick back up.
